Our slide on our playground lifts easily so we put a tarp under the end to make a slip n' slide and a splash pad! The hose has a 2 dollar sprinkler head on it that sprays straight up! It looks like the head of a watering can:)
It keeps the slide and tarp wet and creates puddles all over for splashing! Good clean(cheap) FUN! The tarp is from Costco! It comes in a 2 pack for 20 bucks and we use them for lots of other things. It's 16 by 10 feet:)
